Dancing with Python

By: Robert S. Sutor

Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

7.13 Inheritance

Starting from one class, we can derive other classes that inherit and modify the original’s behavior and functionality. Inheritance allows us to specialize instances while reusing code from the class hierarchy.

In section 1.10, we focused on Bay leaves, but here we return to guitars and their various types. Let’s begin with a basic definition of the Guitar class. The full and documented code that we develop here is in Appendix D.

class Guitar:
    def __init__(self, brand, model, year_built, strings=6):
        self._brand = brand
        self._model = model
        self._year_built = year_built
        self._strings = strings

    def __str__(self):
        return f"{self._strings}-string " \
            + f"{self._year_built} " \
            + f"{self._brand} {self._model}"
print(Guitar("Fender", "Stratocaster", "2012"))
